Osteoporosis is a medical, social and economical problem for developed countries. Prevention remains the only realistic approach to reduce the burden related to this disorder. Primary prevention of osteoporosis is based on efforts to reach a maximal peak bone mass at the end of the growth period and, subsequently, at the time of menopause. No pharmacological intervention is considered at this stage. Biologically, hormone replacement therapy induces a correction of the biochemical changes observed in markers of bone remodeling at the time of the menopause. A systematic screening of asymptomatic postmenopausal women followed by the induction of hormonal replacement therapy in high risk subjects appears to be an interesting cost/benefit strategy in terms of reasonable attribution of health resources. Nasal administration of calcitonin fully prevents the trabecular bone loss observed during the first years of menopause. Notwithstanding, the exact dose of nasal calcitonin able to prevent bone loss remains to be fully elucidated. Bisphosphonates inhibit bone resorption. Tiludronate prevents trabecular postmenopausal bone loss. The use of selectif estrogen receptor modulators is based on a possible differential action of these molecules, at the level of the estrogenic receptors, depending of the tissue considered. Several direct inhibitors of osteoclastic resorption are also under development. Their main target is either to prevent the linkage of osteoclasts to the bone matrix or to prevent the acidification of bone matrix required to induce the resorption process. [less ▲]

A cold-active alpha-amylase was purified from culture supernatants of the antarctic psychrophile Alteromonas haloplanctis A23 grown at 4 degrees C. In order to contribute to the understanding of the molecular basis of cold adaptations, crystallographic studies of this cold-adapted enzyme have been initiated because a three-dimensional structure of a mesophilic counterpart, pig pancreatic alpha-amylase, already exists. alpha-Amylase from A. haloplanctis, which shares 53% sequence identity with pig pancreatic alpha-amylase, has been crystallized and data to 1.85 A have been collected. The space group is found to be C222(1) with a = 71.40 A, b = 138.88 A, and c = 115.66 A. Until now, a three-dimensional structure of a psychrophilic enzyme is lacking. [less ▲]

The trisaccharide Gal alpha 1-->3Gal beta 1-->4GlcNAc beta 1-->O-(CH2)8COOCH3 was enzymatically synthesized, with in situ UDP-Gal regeneration. By combination in one pot of only four enzymes, namely, sucrose synthase, UDP-Glc 4'-epimerase, UDP-Gal:GlcNAc beta 4-galactosyltransferase and UDP-Gal:Gal beta 1-->4GlcNAc alpha 3-galactosyltransferase, Gal alpha 1-->3Gal beta 1-->4GlcNAc beta 1-->O-(CH2)8COOCH3 was formed in a 2.2 mumol ml-1 yield starting from the acceptor GlcNAc beta 1-->O-(CH2)8COOCH3. This is an efficient and convenient method for the synthesis of the Gal alpha 1-->3Gal beta 1-->4GlcNAc epitope which pays an important role in various biological and immunological processes.

The purpose of this study was to follow the recovery of horses during 1hour after treadmill exercise performed either in temperated atmospheric conditions (TC) (ambient temperature: 15°C; relative humidity: 55%) or in hot and humid conditions (HHC) (ambient temperature: 30°C; relative humidity: 75%). Five healthy fit standardbred horses (493± 14 kg; 4± 0,5 yrs) were investigated twice at eight days interval, in TC and in HHC. Some ventilatory and cardiorespiratory measurements were made during a standardised treadmill exercise test (SET), other measurements, i.e. cardiac and respiratory frequencies and rectal temperature, during a 1-hour recovery period. The SET consisted in 8 min warm-up and in 8 min exercise (1 min at 1,7, 4, 7, 8, 9 and 10 m/sec and 2 min at 4 m/sec with a 6% (3.4°) slope). Venous blond was sampled before, 2 min, 60 min and 48 hours after the completion of the test for biochemical analysis, namely plasma electrolytes and enzymatic activities. Exercising in HHC induced a reduction of the aerobic metabolism to the total energy requierement, i.e. a 20 % decrease of VO, and 55 % increase in lactate, as well as a decrease in VE. The increase in rectal and skip temperature, the dehydration and the weight loss were higher in HHC than in TC. During the recovery period the HR and f remained higher up to 30 minutes after the end of the SET in HHC while the rectal temperature remained higher up to 60 min after the end of this test. Sa, despite the fact that our horses recovered in TC after exercising in HHC, there were significant differences between their physiological parameters measured during the recovery. This means that the recovery in air-conditionned unit would probably be an insufficient measure to ensure an adequate cooling of the horses and justify consequently the adaptations proposed by the FEI, i.e. the decrease of the distance of the run and the increase of the lime devoted to the hall between phases [less ▲]

An inheritable muscular hypertrophy was recently described in sheep and shown to be determined by the callipyge gene mapped to ovine chromosome 18. Here, the callipyge phenotype was found to be characterized by a nonmendelian inheritance pattern, referred to as polar overdominance, where only heterozygous individuals having inherited the callipyge mutation from their sire express the phenotype. The possible role of parental imprinting in the determinism of polar overdominance is envisaged. [less ▲]
